Abstract
Description
A waterproof LED wall light for bathroom Technical Field
[0001] This utility model relates to the field of lighting fixtures technology, specifically a waterproof LED wall lamp for bathrooms. Background Technology
[0002] In a bathroom environment, due to the humidity and moisture, ordinary wall lights cannot meet waterproofing requirements. Currently, most bathroom wall lights on the market have numerous problems.
[0003] On the one hand, some wall lamps have poorly designed waterproof structures and inadequate sealing of the lamp housing, allowing moisture to easily enter the lamp through gaps, causing short circuits and damage to the LED beads, thus significantly shortening the lamp's lifespan. On the other hand, even if some wall lamps have a certain degree of waterproofing, their heat dissipation performance is poor. After prolonged use, heat accumulates inside the lamp, accelerating the aging of electronic components, which not only affects the lighting effect but also poses safety hazards. Summary of the Invention
[0004] To address the aforementioned technical problems, this utility model provides a waterproof LED wall lamp for bathrooms.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] This application provides a waterproof LED wall lamp for bathroom, including a lamp body housing, which is composed of a front shell and a rear shell. The rear shell is sealed to the rear end of the front shell. The side wall of the front shell forms an upward angle from the front end to the rear end. A lampshade is integrally formed at the front end of the front shell. A straight cylindrical inner shell is provided on the inner wall of the front shell. A light-emitting component is provided inside the straight cylindrical inner shell. An inner sealing cap is connected to the free end of the straight cylindrical inner shell by a threaded connection.
[0007] Preferably, the front shell has an assembly ring at its rear end, and both the assembly ring and the mating part of the rear shell have sealing grooves, with sealing rings provided in the sealing grooves.
[0008] Preferably, the outer wall of the straight cylindrical inner shell is provided with heat dissipation fins, which extend to the outer side wall of the front shell.
[0009] Preferably, the light-emitting component includes an integrated board, on which a lamp board and a power driver are provided, and the lamp board and the power driver are connected by a waterproof connector.
[0010] Preferably, the light panel is provided with a number of LED beads.
[0011] Preferably, the free end of the straight inner shell is provided with an internal thread section, the side wall of the inner sealing cover is composed of a connecting inner layer and a snap-fit outer layer, the outer wall of the connecting inner layer is provided with an external thread section, the internal thread section and the external thread section are threadedly engaged, and the outer wall of the internal thread section is in contact with the inner wall of the snap-fit outer layer.
[0012] Preferably, a waterproof ring is provided on the bottom surface between the inner connecting layer and the outer snap-fit layer.
[0013] Compared with the prior art, this utility model provides a waterproof LED wall light for bathrooms, which has the following advantages:
[0014] 1. The front and rear shells of this utility model are connected by a waterproof seal. The lampshade and the front shell are integrally molded, forming multiple layers of waterproof protection, effectively preventing moisture from entering the lamp's interior. A straight cylindrical inner shell is installed inside the front shell, with an inner sealing cap threadedly connected to it, thus forming secondary waterproofing. Furthermore, the sidewalls of the front shell rise at an angle from the front end to the rear end, effectively preventing water droplet accumulation. This greatly improves the waterproof performance of the wall lamp, effectively protecting the internal electrical components and extending the lamp's lifespan.
[0015] 2. This utility model incorporates heat dissipation fins in the inner cylindrical shell, which extend to the outer side wall of the front shell. This increases the heat dissipation area and accelerates the heat dissipation rate, enabling the heat generated inside the lamp to diffuse to the outside of the lamp. This prevents the electronic components from aging due to heat accumulation inside the lamp, ensuring the stability of the lighting effect and reducing safety risks.
[0016] The features and advantages of this utility model will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0022] Referring to Figures 1-3, this application provides a waterproof LED wall lamp for bathroom, including a lamp body shell 1, which is composed of a front shell 2 and a rear shell 3. The rear shell 3 is sealed to the rear end of the front shell 2. The side wall of the front shell 2 forms an upward angle from the front end to the rear end. A lampshade 4 is integrally formed at the front end of the front shell 2. A straight cylindrical inner shell 5 is provided on the inner wall of the front shell 2. A light-emitting component 6 is provided inside the straight cylindrical inner shell 5. An inner sealing cover 7 is connected to the free end of the straight cylindrical inner shell 5 by a threaded connection.
[0023] Referring to Figures 1 and 2, specifically, the rear end of the front shell 2 is provided with an assembly ring 21, and the assembly ring 21 and the rear shell 3 are both provided with sealing grooves 22. A sealing ring 23 is provided in the sealing groove 22, and the sealing ring 23 can isolate external moisture to form an external waterproof effect.
[0024] Referring to Figures 1 and 2, specifically, the outer wall of the straight cylindrical inner shell 5 is provided with heat dissipation fins 51. The heat dissipation fins 51 grow to the outer side wall of the front shell 2. The heat dissipation fins 51 can diffuse the heat generated inside the lamp to the outside of the lamp, avoiding the aging of electronic components due to heat accumulation inside the lamp.
[0025] Referring to Figure 1, specifically, the light-emitting component 6 includes an integrated board 61, on which a lamp board 62 and a power driver 63 are provided. The lamp board 62 and the power driver 63 are connected by a waterproof connector 64.

[0029] The working principle of this utility model:
[0030] One-time waterproofing: The front shell sidewall rises at an angle from the front to the rear, which effectively prevents water droplets from accumulating and avoids prolonged immersion of the lamp in large amounts of water. This protects the lamp body shell while reducing the possibility of water entering the lamp. The sealing ring 23 located between the front shell 2 and the rear shell 3, along with the integral molding of the lampshade and the front shell, forms an outer sealed space to prevent water mist from entering, thus providing one-time waterproofing.
[0031] Secondary waterproofing: The inner sealing cover 7, together with the straight inner shell 5, can form an inner sealed space, and the inner layer 71 and the outer layer 72 are connected to form a double-layer structure. With the waterproof ring 74, it can further achieve the waterproofing effect, thus forming a secondary waterproofing function.
[0032] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
